Car dumping fuel

[Adhamkhe]

Hi everyone
Car is m20b28( modified engine)
Running 405 ecu and wiring( I know it's for M50)
The car drives perfectly when the chip is first installed then after 30 minutes it goes super rich
Checked the temperature sensor it works normal
Any suggestions???

Both motors m20 and m50 have two temperature sensors each, one goes to the DME, the other to the instrument cluster

Thanks for the reply. The blue sensor is the one that was replaced ( going to ecu ) problem remains

Maybe Found the issue. The camshaft sensor wasn't connected properly. Will fix it and update
